(a,b) Natural abundance, (c,d) adult transplant survival and (e,f) recruitment success for Hexastylis arifolia and Hepatica nobilis as functions of soil moisture (volumetric (%)) and diffuse light ((%) photosynthetically active radiation penetrating the forest canopy). The response surfaces are parametrized with the fitted coefficients from the regression models that best predicted Hx. arifolia and Hp. nobilis abundance in (a,b) natural populations, (c,d) adults transplanted into experimental plots and (e,f) seeds grown in experimental plots.
